Incomprehensible problem
-
Hello everyone,
Well I still have a problem with my DUET WIFI, I think earlier that it is a problem of setting, but I can not understand what I do wrong …
So I could not calibrate my nozzle properly,
That is my way of doing things.1: I lower the nozzle until touching a sheet of paper on the tray.
2: I look at the value of Z for example "1,50",
3: I put the g code G92 Z0, the value of the Z axis changes to 0,
4: I go into the config file and here:
Z probe and compensation definition
; *** If you have a switch instead of an IR probe, change P1 to P4 in the following M558 command
M558 P1 X0 Y0 Z0; Z probe is an IR probe and is not used for homing any axes
G31 X0 Y0 Z1.50 P500; Set the zprobe height and threshold (put your own values here),
I get my value find here 1.50.Once that is done if I try to do a G1 Z0 F3000, my nozzle will sink into the tray,
Do you have an idea,
Thank you -
What is the Z value when the nozzle touch the surface when you have Z1.50?
Maybe try setting Z-1.5 in your G31 instead.I always have trouble dealing with the +/-, all I have done was trial and error
Someone else could probably give you a more scientific approach -
thank you for your reply,
Not the value is +1.50.
I am forced to go up the buzzard so it's much more I think. -
do you have a Z Probe?
If so what type is it? -
Yes I have a BL TOUCH
-
I believe the offset is only applied during the probing calculation, so you need to do another calibration before the offset is actually applied to the max print height.
-
The value for Z in the G31 line needs to equal the hight of the nozzle above the bed when the BLtouch triggers.
-
If my BL Touch is too high this can be a problem?
-
Well I'm really fooling with this machine,
It's been 3 whole days now that I try to do something with it but without success,
I think I will leave it aside and continue with my BLACK WIDOW that works really well,
One last question before I go through the window: what distance do you put between the BL TOUCH when the probe is in and the nozzle?
Is there a risk in making an update of the DUET WIFI,
Thank you for your patient -
If my BL Touch is too high this can be a problem?
Yes, it could be so high that it doesn't trigger before the nozzle hits the bed.
With any Z probe, you should always test it, measure it's trigger height and put that value in the G31 command in config.g before you try to use it for homing of bed probing.

Hello,
I'm still looking for my calibration problem.
I do not know what is wrong,
So here is the method that I practice,
1 - I lower my head until I catch a sheet on the board,
2- I then make a G92 Z0
3- I raise the head to about 50mm
4- I release the BL TOUCH
5- I lower the head until the BL TOUCH goes up and lights up
6- I open my config file and change the value here;
Z probe and compensation definition
; *** If you have a switch instead of an IR probe, change P1 to P4 in the following M558 command
M558 P1 X0 Y0 Z0; Z probe is an IR probe and is not used for homing any axes
G31 X0 Y0 Z1.65 P500; Set the zprobe height and threshold (put your own values here),And when the machine restarts I make G1 Z0 F1500 and the head come to sink a big blow in the plate,
What am I doing wrong?
Thank you -
for a start you have your config set for a IR Probe and not a BLtouch there is a thread on here about how to use a BL Touch.
-
I created a mount for my BLTouch that's connected to my Duet WiFi and included a number of Duet WiFi configuration/script files. It works good and you should be able to use them for a reference and the macro files to run your BLTouch.

Thank you for your answers, I'll look at it later; I have to look at another problem "I really have no luck with this machine"
I miss the update of the DUET WIFI
